. feed-lever is actuated.

Numeral reference characters are used;

InVFigs. 1'2, 18, and 1-9 the drivin' -shaft 1" is shown yieldinglyconnected with t 'epliltch ,member 2 in conse dance of the shaft being through a hole in said-blotch member and. in consequence of the lug 3 being fast to the :shaft 1 and connected with the sprin 4, so that no great shock is 'ven to the she t! by the violent starting. 0 .said clutch member. Fig. ISshows the end' of said clutch member 2 with the cover shown in Fig. 2G'removed. Fig. 19 shows a longitudinal section of Fig.18 on-line 20 20 in said figure; Fig. 21 shows a owls. (Shown also in Figs. 17 18, and 19.) T s pawl is adapted to be thrust into the position in which it is shown by its spring 6 shown therein, so that the oint of said 'awl may enter the groove 7 in t 1e belt-whee 8, a part of which is shown in Fig. 22, when said pulley is loose on the shaft 1 andis'in the position in which it is shown in Figs. 1 and 5, so that the clutch device 9 in said groove 7 may catch the point of the pawl 5 to start the clutch member 23nd the driving-shait l of the main mechanism. In Fig. l the inclined end of the stop-fork 10 (shown in Fig. 7 is shown held into the groove 11, shown in the clutch member 2, byits spring 12 and against the inclined shoulder of said pawl5 (shownin Figs. 21 and 17) so as to holdthe pawl 5 back against the force of its spring 6 and out of the groove? (shown in Fig. 22)by the spring 12, (shown in Fig. 1,) fast to a pin in said stopfork l0 and a in in the hub of the lever 13.

in Fig. 3 the Support 14 is shown secured to th bottom of the machine by screws. In Fig. .3 this support is shown to have an upri ht round part 15, (shown in section,) in w iich said lower journal 16 of said yoke is rotatably supported, and is also shown in section. Upon said round part the caindisk 17 (shown in section and having two cam-iaces-vi7.., l 8 and 19, shown in Fig. 2)- and a cam-face 20 and a ratchet '21 (shown in Fig. 3) is rotatablysupported. The strikeriever 2'2 and the feed-lever '23 are also shown in Section on said round part 15, and the pswls 24 of the feed-lever are in contact with the ratchet 21, as is plain in Fig. 23 at the left. Before said stop-fork is automatically inserted into the position as above described and as shown in Figs. 1 and 5 the clutch member 2 may be turned by hand or by any non-automatic means, whereupon the b ock 25 on the sc ew 26, fast in a slide fast to the clutch member 2, is moved back and forth in the slot in the lever 13 and rocks lever 13 on its pivot-screw 27, fast in the frame of the machine, whereupon the lever 13 vibrates the rod 28, pivoted thereto, and rocks said striker-lever, pivoted to said rod on said round part 15, and the feed-screw 29, carried by said striker lever, strikes the block 30, movably sup orted on said feedlever 23, said block aving a stud with a roll 31 thereon and in contact with cam-face 20, as shown in dotted lines in F i 3 and in full in Fi 5, and moves said fee -lever and pawlsi, w ich, being in contact with said ratchet 21, (shown in Fig. 3,) moves said ratchet 21 and cam-disk fast to said ratchet, and as the cam-disk has the cam-faces above described they are moved, the ratchet device 32 on the right in Fi 3 preventing backward movement of t e cam-disk and the friction-band 33 (shown in Figs. 5 and 3) preventing overthrow thereof, and the spring 34, shown fast to the feed-lever 23 and fast to a hook in the bed of the machine moving the feed-'lever in the opposite direction from the movements imparted thereto by the striker lever,.the movement of the feed-lever being limited by the stop-screw 35 (shown in Figs. 23 and 3) striking the 'sup' ort 14. The camdisk being thus moved, t e roll 36 in contact therewith and on the stud 37, fast in slide 38 in slideway 39, (shown in Fig. 4,) moves said slide 38 and stud 37, fast thereto, and as the block 40 is fast to said stud 37 said block is moved, and as the clamp-plate 41 is pivoted to this block, as is shown in Fig. 4, the clampplate 41 and clam s 42 and 43 and a material therein are mover and as the slot 44 in said clamp-plate (shown also in Fig. 14) is over the block 45 (shown in Figs. 2 and 15) and as the block 45 is movably supported on the screw 46, fast in lever 47, fast to stud 48, which is movably su ported in the rigid support 49, and as the ever is also fast to the stud 48 and has a roll 51 movably secured to the screw 52, fast in said lever 50, and as the roll 51 is held in contact with the cam-face 19 by the spring 53, fast to the lever 47 and to a hook in the side of the machine, and as the block 45 fits the slot 44 sidewise, the clamp-plate is swung sidewise by said block and 1s ided by said block, and the clamps on sai clamplate and the material therein are thus move dia onally of the first movement imparted to sai clamp-plate and clamps, the round part 113, whereu on the clamps may be separated, (shown in igs. 13 and 16,) on the evice,114, the position of which is shown by dotted lines between the clamps in Fig. 14, swinging on its pivot 1 15, (shown in Fi 16,) permitting. While the cam-disk is tius moved longitudinally and diagonally of the clam s, the yoke, (shown in Fig. 8,) with the need e-bar bearin s 54 and 55, (shownjn Figs. 9 and 10,) fast tl iereto, as shown in Fig. 5, the block 56, fast to and carried by the cam-disk and shown in Figs. 2 and 15, is brought into contact with the slidebar pin 57, fast to the slide-bar 58, movably mounted in the bearings 59 and 60, and said' yoke, the lower 'ournal of which is pivoted, as aforesaid, and the top journal of which is ivoted in the head of the machine, is turned in its bearings gradually, or little by little, and after it is turned one half-revolution and is carried into the position shown in Fig. 5 and o erates the latch 61 (shown in Fig. 11) at t e next movement the slide-bar pin is forced against the inclined end of the adjustable disconnectin -bar 62, and is thereby disengaged from t e block 56 by the slide-bar, be- -1ng thereby slid in its bearings 59 and 60 against the force of the spring 63, fast to said slide-bar and to a pin in the yoke, and shown in Fig. 5, whereupon the cam-disk is moved on without carrying the yoke, and while the yoke is prevented by said latch 61 from being rapidly turned in the opposite direction by the mainspring 64, secured to the rigid post 65 and to the strap 66, secured to the clamp .67, fast to the lower journal of said oke and shown in Fig. 3, which main spring ad been gradually expanded by said yoke as it had een turned. Durin the time that the clutch member 2 an 'shaft 1 is manually turned, as aforesaid, the eccentric 68 and eccentric strap 69, connected therewith, is moved, whereupon the lever 70, pivoted to said eccentric-strap, is rocked on its pivot 71, and throu h the ball-and-socket connection between t e lever and the needle-bar the needlebar is forced to cause the needle therein to produce an effect upon a material to be operated u on in said clamps, and the eccentric 72 is a so moved in the forked end of the forked lever 73, whereupon the forked lever is rocked on its ivot 74, fast to the arm of the machine, an a roll 75, movably secured to the lower end of the forked lever 73, is moved back and forth in the slot 76, shaped somewhat like a half a rhombus, in the lever 77, pivoted on its pivot-screw 7 J, and through the ball-and-socket connection between this lever and the lower needle-bar the needle in this bar is also forced to produce an effect upon the material.

The automatic action of the machine is described as follows: When the clamp-lever 79 is pressed, its toe 80 is thereby moved out of its vertical position, whereupon the hinged forked lever (shown in Figs. 14 and 1) under the stress of the spring 112 is forced thereby to seize the material, and a rod (not shown) may be connected with the clamp-lever H3 fast to two around the case and the operation is finished or when enough power is generated and stored a device 101. (shown on the cam-disk in Fig. 2) forces a device 102 upon the buffer-spring 89 instantly forces the bufier-rod to rebound and carr r nesting-rod 94, hingedtothe buffer-rod 88, to the right in Fig. 1, thereby releasing'the' roll 98 on theconnecting-lever 99, whereupon the spring 103, fast to connecting-lever 99 and to the machine, tips the connecting-leverand, moves its right-hand end downward, whereupon the spring 12, secured to said stop-fork, instantly pulls the inclined end ofthe stopfork 10 into the groove in the clutch member, whereupon the inclined shoulder of the strikes said inclined end of said stop -fork, and the pawl is thereby quickly forced out of contact with the driving-clutch member 2, there for operating the latch or trigger 61, thereby releasing the power in the inainspring 64 of the auxiliary mechanism, whereupon the storedpower released instantly operates the bearings, and the device 81, carried by said yoke Fig. 15, is struck pawl and shown in against the'cam device 82 postsfast to the clam late, an

said cam clamp-plate and materialt erein are moved quickly into cutting position against the force of the spring 83, shown fast to the m Fig. 4) under the front .end 0 the clam said yolib the toe of the pawl device 85, hinged in the cutter-lever 86, and the cutter 87, carried by said cutterlever, is forced to produce an effect on a maby disconnectin the clutch members, thereby terial on a rawh de cutter-block, (shown automatically isemploying the continuous best in Fi 13,) and when the pawl device 81 power and automatically stopping the main has passe by the cam device 82 said spriiw mechanism from operatin on the material and yielding catch 104, (s io'wn in Fig. L8,) movahly secured to the clutch member 2 by two screws 105 and 106 in a slot shown thercin, and fast in said clutch member and fast to the spring 107, fast to a screw in said clutch member, is forced by the violentlv- D 83 instantly brings the' clamp-plate clam s and material into sewing position, and at tile same time the yoke is forced against the buffer-rod 88, drivin it back against the force of its powerful iufl'er spring 89 (shown buffer-rod in the slot in the butlerto trip the butler-latch 91, where- .80 pawl 5 i hearing against a shoulder on said 1 moving parts down on the tine 108 of the stop butler-rod) and against the back end of the fork 10, {shown in Fig. 1,) and as the momenuffer-case, and said bufl'er-rod is instantly turn is nearly exhausted acting a e-inst the latched back bythe buffer-latch 91, (shownin spring the rigid catch 109 is caug t by the Fig. 4,) being caused tohook onto the proection 92 on the device on the side of the ufi'er-case by the buffer-latch spring 93, and the force of the yoke is thereby diminished and power is thus automatically generated and stored in the butter by the yoke forced j by storedpower released, and while the buf- J fer-rod is thus forced hack the connectin f rod 94, hinged to the bufler-rod is forced In '1.
